Diallyl disulfide reacts within minutes with liquid sulfur at 120°C giving a family of diallyl polysulfanes, All2S n (n=3–22), characterized by ultra-performance liquid chromatography-(Ag+)-coordination ion spray-mass spectrometry (UPLC-(Ag+)CIS-MS). Similarly, garlic oil (GO), bis-(2-methyl-2-propenyl), bis-(2-chloro-2-propenyl), bis-(3-methyl-2-butenyl), and bis-(2-cyclohexen-1-yl) disulfides all give families of polysulfanes with up to 22 sequential sulfur atoms. New members of families of…
